Tomorrow I'll be in Belfast to give evidence on behalf of Suzanne Breen, the journalist fighting off a demand by the police to hand over her notes, phones and computers in order that they can discover the sources of her stories.

The Police Service of Northern Ireland made an application under the terrorism act following Breen's revelations about the Real IRA in the Dublin-based newspaper, the Sunday Tribune. She is the paper's northern editor.
